[1/1 Formula]
    Work: Calculate the value of equation ((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500)) .
    Question type: Mathematical calculation
    Solution:
          ((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500))
        =((0.005×(1-cos0.001328))/cos(83/62500))/(tan(83/62500)-(83/62500))
        =((0.005×0.000001)/cos(83/62500))/(tan(83/62500)-(83/62500))
        =(0/cos(83/62500))/(tan(83/62500)-(83/62500))
        =(0/cos0.001328)/(tan(83/62500)-(83/62500))
        =0/(tan(83/62500)-(83/62500))
        =0/(tan0.001328-(83/62500))
        =0/(tan0.001328-0.001328)
        =0/0
        =-nan

    Answer:((0.005×(1-cos(83/62500)))/cos(83/62500))/(tan(83/62500)-(83/62500))=-nan
